MAGNETIQSLUG DEFLECTOB. FOR GOIN CONTROLLED MACHINES Specification of Letters Patent.

Patented hpr,2,1918,

Original application filed December 17, 1914, Serial No. 877,647. Divided and this application filed July 3,

1916. Serial No. 107,229.

To all whom it may concerni' Be it known that I, ALBERT Gimme, a

citizen of the United States, and a resident This application is a division of my copending application, Serial No. 877,647,

filed December 17, 1914, and I have, therefore,

' not deemed it. necessary to illustrate more than a section of the coin-chute with the associated magnetic deflector. I The drawing accompanying this specification comprises a single figure which shows a iongitudinal sectionof a coin-chute provided with my invention.

The upper opening 1 of the coin-chute is arranged in alinementwith the coin-entrance slot of the machine, while the lower or exit end 2 is adapted to guide the coin into proper position within the machine. As it is not necessary to an understanding of my invention what the coin does after leaving thecoin-chute, no coin-controlled mechanism need be shown or described; A permanent ita -shaped magnet M is so fixed in position,

. by any suitable means, with respect to the hem-chute that the upper edge 3 thereof is.

substantially parallel with the wall 4 of the coin-chute. The magnet, or at least that portion of it which extends into the coinchute, is arranged in the plane of the coinchute itself. The upper edge 3 of the mag net and the wall 4 form the first section oi the zigza coin-chute. The vertical wall or edge 5 o the coin-chute comes opposite the point 6 of the pole p of the magnet, whlle the wall 7 is substantially parallel to the polar faces 8.. The angular arrangement of the wallsfi and7 is such that the deposited coin or check will roll closely about the point 6 and then pass in very close proximity (as closely as mechanical conditions will permit) to the polar faces 8..

When a good coin is deposited, it passes from between the polar faces 8 and the wall 7 into the passageway 9 formed by the parallel walls 10 and 11, and thence downwardlypole p, which forms the last point of contact between the magnet and the-magnetic disk.

In proper position with respect to the edge 12 of the magnet is fixed a non-magnetic pin or stud 13 which extends into the plane of the magnet,1or at least of the poles thereof. Now, as the descending magnetic disk swings about the point 12, it strikes the pin 13 and thereby breaks contact with the magnet, with the result that the disk falls out of the coinchute through the discharge opening 14 formed between the magnet, and the upper edge 15 of the wall 11. In drawing, the dotted circle G indicates either a good coin or a magnetic disk as it begins to roll past the polar edges 8. The dottedv circle G- indicates the position of a magnetic disk which has been stripped from the polar edge 19, by coming ihtocontact with the tired pin 13 and is ready to drop out or" the coin-chute through the opening 14.

It will be seen from the above that 1 have provided a very simple and effective deilector for magnetic slugs. My invention is pan ticularly effective for diverting thin, light magnetic disks which are usually very diiil- Cult to get rid of in coin-controlled machines and frequently cause considerable trouble, as actual experience has-shown.

Another advantage of my invention, as will be clear from the above, resides in the fact that magnetic slugs are positively prevented from beingsnapped past the magnet. This is due to the arrangement of the mag net, or at least the poles thereof, to form part of the inclined wall of the coin-chute.

If the inserted coin should be snapped into .the coin-opening 1, it will first strike the edge 3 of the magnet and then roll into the angular space formed by the walls 5 and 7, so that when the inserted disk begins to roll over the inclined wall 7 past the polar faces, it wili have lost all of its initial velocity and will simply roll down by gravit T with sutficent slowness to allow the magnet to exert its full influence on the disln Even it a person should succeed-in speeding the inserted magnetic slug over the edge 3 of the magnet, its increased.momentum (that is to say, the

momentum due to an initial velocity) will be eliectively arrested by the walls 5 and 7,

While l have herein shown a specific configuration and arrangement of coin-chute and magnet, I would have it understood that I do not intend to be limited to such details, as the shape, proportion and arrangement of the parts may be modified and still embody the invention as described in the appended said inclined loottom wall in magnetic con-* tact with both polar faces, and a nonsnagnetic stop arranged nearthe lower pole-tip oi the magnet to strip the magnetic disks inaeniai from said pole-tip and swing them out oi the coinchnte.

2. In a coin-controlled machine, acoinchute having a downwardly inclined ooinentrance section and a downwardly inclined coin-testing section arranged at an angle to said first section, so that the momentum of a deposited check is arrested in passing from the first section to the second, a downwardly extending Ill-shaped magnet so mounted that its upper limb forms the lower wall of said coin-entrance section and the polar faces form the top oi? said inclined coin-testing section, whereby a deposited check rolls over said upper limb and is then forced to travel through said section under both polar faces in close proximity thereto, so that a magneticchecli: rolls past said polar faces in magnetic contact therewith, and a non-ma e netic stop arranged near the lower pole-tip of the magnet to stri the magnetic disks from said pole-tip an swing them out of the com chute.

In witness whereof, ll hereunto subscribe my. name this 29 day of June, 1916.
